A further object of my invention is the provision of novel means for forming the packers them selves, and novel means for actuating the packers, whereby, say, every fiftieth napkin or towel, as the case may be, is advanced a slight distance above the stack, to indicate the number of towels or napkins in the receiver.

A further important object of my invention is to provide a pair of receivers below and on opposite sides of the cutting rolls or cylinders, with means for guidingthe severed folded sheets between the receivers and an oscillating packer for alternately carrying the sheets from the guides into the oppositely disposed receivers.

A still further object of my invention is to provide a novel paper-folding, cutting, and counting machine of the above character, which, will be durable and eflicient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 21 is a detail perspective view of one of the tucking blocks.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter M generally indicates the improved paper folding and cutting vmachine, and the same may comprise a pair of like, transversely alined, spaced side plates 20 and 2!, to form a support for the various operating parts of the machine. The plates are firmly secured together in any desired manner, and against movement, such as by the use of tie rods or bolts 22. The lower ends of the plates can be joined by a suitable supporting base 23.

Arranged transversely of the machine is the main bed roll or cylinder 24, having formed in its periphery at diametrically spaced points longitudinally extending knife grooves 25. This bed roll or cylinder can be keyed or otherwise secured to a transversely extending shaft 26, journaled in bearings 21, carried by the side plates 20 and 2|.

The paper web or strip 28 is adapted to be drawn over the face of the bed roll or cylinder 24, and is held in frictional contact therewith by friction pull pressure rollers 29 and 3|]. These pressure rollers may have their outer surfaces covered with felt, or other cushioning material, and engage the bed roll or the paper strip traveling over said roll at spaced points and on opposite sides of the vertic'al, diametrical center of said bed roll.

The terminals of the pressure rollers 29 and 30 are journaled in suitable bearings carried by the end or side plates 20 and 2|, and the terminals on one side have rigidly secured thereto pinions 3| and 32, which mesh with a gear wheel 33, keyed or otherwise secured to one end of the shaft 26 for the bed roll or cylinder 24. The bed roll or cylinder 24 is power-driven in any preferred manner, such as from an electric motor 34. The armature shaft of the electric motor can be connected by a pulley belt 35, with a large pulley wheel 36 rotatably mounted on the shaft 26. A manually operated clutch 31 of any desired construction can be utilized for connecting the pulley wheel 36 with its shaft 26.

The web or paper strip 28 is adapted to be pulled off of the paper roll 38 by the bed roll or cylinder 24, and the pressure rollers 29 and 3D, and means is provided. for folding the web twice longitudinally between the paper roll 33 and the bed roll 24.

As illustrated, the paper roll 38 is rotatably mounted on a suitable spindle 39 carried by a supporting frame 40 located at one side of the machine M, and the upper end of the frame 46 is connected to the machine by longitudinally extending, spaced parallel side bars 4i. These side bars 4| carry paper-folding guides 42 and 43. These guides 42 and 43 are of conventional construction, and will not be described in detail, but each includes an ordinary forming plate, and the first guide 42 folds over the longitudinal edges of the paper web 28 on the main portion of the web, as indicated by the reference character 44 in Figure 11. The second folding guide 43 again longitudinally folds the edges of the web or strip, as indicated by the reference character 45 in Figure 12 of the drawings.

The parallel longitudinal bars 4! carry a guide roller 46 above the paper roll 39, and the paper strip or web is led over said guide roll, through the first folding guide 42, and then over a second guide roller 41 carried by the bars 4!, and then through the second folding guide 43. The twice-folded web or strip 28 is then placed over the bed roll or cylinder 24 under the pressure rollers 29 and 30. Obviously, as the bed roll or cylinder 24 is driven, the same will pull the paper web .or strip off of the paper roll 38 through the folding guides.

As the folded paper web or strip 26 travels over the bed roll or cylinder, the same is partially severed transversely into equally sized sheets. To bring aboutthe partial severing of the strip the cutting roll 48 is provided, and this cutting roll is arranged above the bed roll 24 and between the pressure rollers 29 and 36. This cutting roll 28 is keyed or otherwise secured to a transversely extending shaft 49, which is rotatably mounted in suitable bearings 50 carried by the side or end plates 20 and 2|. One end of the shaft 49 has rigidly secured thereto a pinion 5|, which meshes with the main gear wheel 33 on the shaft 26 of the bed roll 24. Thus, the cutting roll 48 is also powerdriven.

As brought out. in the objects of the specification, one of the main features of the invention is to handle the paper substantially in strip form throughout practically the entire operation, and hence the cutting roll does not entirely sever the strip, and a knife blade 52 is employed having a center blank portion 53. The knife blade 52 is disposed longitudinally of the cutting roll 48, and is set into a groove formed in said roll and is readily held in said groove by the use of suitable set screws, or the like. The cutting roll with its knife is so set that upon each revolution of the roll 48 the knife will mate with one of the grooves 25 in the bed roll, and the knife will thus enter a groove and partially cutting the strip.

As the partially cut strip leaves the bed roll 24, the same is pulled down, and is then cut at its center by the relatively small cutting and bed rolls 54 and 55. The cutting roll 54 carries a longitudinally extending peripheral knife bladz 56, which is adapted to enter into a groove 51 formed in the small bed roll 55. As the blade 56 is provided with a center cutting edge, thr strip will be cut the rest of the way to form the folded sheets. The ends of the bed and cutting rolls 54 and at one side have keyed or otherwise secured thereto intermeshing pinions 58, and one of these rolls on the other side has rigidly secured thereto a sprocket wheel 59. This sprocket wheel 59 is connected by a sprocket chain, with a relatively large sprocket wheel 59' keyed or otherwise secured to the main bed roll shaft 26.

Below and on each side of the cutting and bed rolls 54 and 55 are receiver troughs 66 and 6! for thefolded and severed sheets. These receiving troughs are of a U shape in cross section, and can be provided with a double bottom wall, with means for adjusting the angle of the top plates of said bottom walls.

As the sheets are severed, they are guided down between the receivers 60 and 6i by means of flexible guide ribbons or tapes 62. These tapes 62 are connected at their upper ends to tension springs 63, which are in turn connected to adjacent tie rods or bolts 22. These tapes are brought over the rolls 54 and 55, and are secured at their lower ends below the receivers to brackets 64 carried by the side plates 20 and 2!. As shown, the tapes are arranged in pairs on opposite sides of the longitudinal center of the folded sheets, and the sheets slide downwardly with their edges between the tapes of the pairs of tapes.

As the folded and severed sheets ride down the tapes, they are alternately placed in the receivers 60 and 6! by the novel packing and counting mechanism 65, which will now be described.

The packing and counting mechanism 65 forms one of the salient features of my invention, and includes a hollow shaft 66 in which is mounted a longitudinally extending solid rock shaft 81. The hollow shaft 88 is mounted for oscillating movement in bearings 88 carried by the plates 28 and 2|. The shafts 88 and 81 are normally connected together for synchronous rocking movement by means of a friction coupling 89 shown at the righthand side of Figure 5, and the hollow shaft is rocked back and forth by means of a pitman rod 18, which is rockably mounted on a crank pin 1| carried by the main gear wheel 83. The lower end of the pitman rod 18 is connected by a wrist pin 12, with a crank lever 13 rigidly secured to one end of said hollow shaft namely, to the part of the. friction coupling 89 carried by the hollow shaft. The wrist pin 12 can be connected at spaced points throughout the length of the crank lever 19 so that the throw of said lever can be adjusted.

Rigidly secured to the central portion of the hollow shaft 88 by means of a two-part sleeve 14 is a U-shaped radially extending packer arm 15. This packer arm is adapted to move between the pairs of guide ribbons 82 alternately into and out of the receivers 88 and 8|. Obviously, during the rocking of the shaft 88, and the packer arm 15, the folded and severed sheets will be alternately carried into the receivers 88 and 8|.

Disposed between the legs of the U-shaped packer arms isa movable packer arm 18, which is rigidly connected to the solid shaft 81. Normally, the packer arms 15 and 18 are in radial alinement, but at certain times the inner packer arm 18 is advanced on one side or the other of the packer arm 15, so that the inner packer arm 18 may-engage a sheet in advance of normal operation. Thus this sheet will be elevated above the stack of sheets in a receiver to indicate that a certain number of sheets have been placed in the receiver. Consequently, mechanism is provided for rocking the solid shaft 81 independently of the hollow shaft after the hollow shaft has made a predetermined numberof oscillations, say fifty. This means includes a radially extending trip arm 11 rigidly connected with one end of the solid shaft 81. The trip arm 11 normally oscillates between a double-ended trip dog 18, which is rockably mounted equi-dlstant its ends on a supporting pivot pin 19. The lower face of the doubleended trip dog, at one end, is provided with a depending tooth 88. This tooth 88 is normally held in contact with the periphery of a cam Wheel 8| by means of a contractile coil spring 82. As shown in Figure 1, one end of the spring is connected to the trip dog 18, and the other end of the spring is connected to the side plate 28.

The periphery of the cam wheel 8| has formed therein a notch 83 and a radially extending cam lug 84. The lug 84 is arranged in close proximity to the notch 83, and during the rotation of the cam wheel, by means which will be later described, the tooth 88 of the double-ended dog will first ride into the notch 83 to cause the rocking of the dog and the elevation of one end thereof. Thereafter the lug 84 will engage the tooth 88 and cause the rocking of the dog in the opposite direction and the elevation of the other end of the dog above normal.

To bring about the rotation of the cam wheel in proper timed relation to the other parts of the mechanism, the cam wheel has rigidly secured thereto a ratchet wheel 85, which is provided with the preferred number of equi-distantly spaced teeth, say fifty. The cam wheel and ratchet wheel are rotatably supported by a stub shaft 88, and rockably mounted thereon is an oscillating crank lever .81. This crank lever 81 carries a pivoted pawl 88 normally held into engagement with the teeth of the ratchet wheel. on each revolution of the small cutting and bed rolls 54 and 55 the crank lever 81 is rocked to bring about the advancement of the ratchet wheel one tooth. This is accomplished by a pitman rod 89, which is operatively connected to the crank lever 81. The upper end of the pitman rod 89 is mounted upon a crank pin 98 carried by a crank wheel rigidly secured to one end of the shaft of the center cutting roll 54.

In operation of the improved machine, as the severed and folded sheets, indicated by the reference character 9|, are brought down between the guide tapes 82, the shafts 88 and 81 will be.

rocked in unison by the crank 13 through the medium of the friction clutch 89. As the stacking arms Hand 18 operate together, the first folded and severed sheet 9| will be brought into the receiver 88, and the next folded and severed sheet will be brought into the receiver 8|. After the resired number of sheets have been deposited 'in the receivers, the notch 83 will have been brought around into alinement with the tooth 88 on the double-ended trip dogs 18, and the trip dog will rock under the influence of a spring 82 and its righthand end, see Figure 1, will be raised into the path of the oscillating trip arm 11. The trip arm 11 will be momentarily held against further movement, and consequently the inner arm 18 will be advanced for engaging the severed sheet prior to the arm 15, which will carry the sheet up to a raised position above the other sheets 9| in the receivers. wheel 8| rides past the tooth 88, the raised lug 84 will strike the tooth, and the double-ended dog 18 will be rocked in the opposite direction, bringing the end of said dog on the lefthand side in a raised position and in the path of the trip arm 11. This will momentarily hold the trip arm againstmovement when it reaches said raised end, and will swing the stacking arm 18 in advance of the packer arm 15 on the opposite side, raising the next folded sheet 9| to an elevated position in the other receiver. When the lug 84 rides past the tooth 88, the double-ended dog 18 will assume its normal position, and the packer arms 15 and 18 will again be in alinement for normal operation.

' During the initial threading of the web 28 through the machine, the various rolls can be As soon as the notch 83 in the cam' turned by hand, and hence a hand-wheel 92 can be keyed to the top cutter shaft 49.

The improved device is open to certain modifications, and in Figures 13 to 17, inclusive, I have shown another form of the device. In.this form the sheets are folded transversely as well as longitudinally. In these figures, the rotary die or bed roll is indicated by the reference charac-ter'95, and the same is keyed to a rotatable invention just described, the knife |8| has its central portion cut out so as to not sever the sheet at its longitudinal axis.

Below the bed cylinder or dieroll 95 I arrange the combined tucker and cutting rolls I83 and I04. The roll I04 is provided with a longitudinal channel or groove I05 for the center cutting blade I06 carried by the roll I03, and this knife is adapted to sever the web at its center to provide the folded sheets Ill'l. At a point substantially diametrically opposite the groove I05, the roll I04 carries a longitudinally extending tucker blade I118. The paper strip or web 91 is fed downwardly between the two rolls I03 and I04. which are power-driven, and these rolls first make a transverse fold in the sheet, and the sheet is then severed in the center by the blade I66 riding into the groove I05.

The roller I03 is of a special construction, so as to grip and hold the paper during the transverse folding operation. This roller embodies a central solid portion I09 formed on or secured to the shaft III], and movable on the inner portion I09 is an outer sleeve III. The sleeve is provided at spaced points in its periphery with grooves II2, the purpose of which will be later set forth, and the inner part Hill of the roll carries grip blocks H3, which operate in longitudinally extending grooves HQ. The grip blocks III;

are normally urged toward one wall of the groove by means of contractile coil springs M5, the opposite ends of which are secured respectively to the inner portion I89 of the roll, and the outer portion III of the roll.

As the paper strip is fed down between the rolls, the tucker blade I08 rides into the groove II I, carrying the strip therewith in between the gripping blocks H3 and a wall of the groove, and these blocks thereafter hold the paper strip in the groove. Upon continued rotation of the rolls, the strip is carried therewith, as clearly shown in Figure 14, and when the center blade I06 rides into thegroove I in the roll we, the strip will be severed, forming a transversely folded sheet. The sheet is now removed from the tucker roll I03 in a novel manner, and carried into a receiver IIIE. The receiver is in the nature of a U-shaped trough, and is arranged at one side of the roll I83.

The means for stripping the severed sheet from the roll, and into the receiver IIB, includes a rock shaft I II, having loosely mounted thereon a hollow shaft H8. The hollow shaft carries radially extending stripper and packer fingers H9, which are adapted to ride into the circumferential grooves H2 at certain times, which will be later set forth. The shafts III and IIB are cperatively connected together by a springpressed friction coupling I2Il, so that normally the shafts oscillate together as a single unit. The shafts are normally actuated together by the crank IZI connected to the inner shaft I II. This crank I2I can be rocked by the same mechanism employed for thecrank I3 in Figure 3. The outer shaft H8 has secured thereto the trip finger I22, which is operated in the same manner as the trip finger Ii in the form previously described.

Thus, in operation of my improved device, when the takeoff and packer fingers II9 ride into the-circumferential grooves M2, the same ride in rear of the sheet carried by the roll I03. Hence, when a predetermined point is reached, the fingers H9 will move to the left (see Figures 13 and 14) and carry the sheet from between the grip blocks H3 and the wall of the groove IM, and carry the same into the receiver Ild. At certain intervals the outer shaft H8 will be rocked by the trip arm I22, causing the fingers to be advanced, so as to strike the sheet at a different time from normal, and thus elevate the sheet a slight distance above the other sheets in the stack to indicate the number of sheets in the receiver.

Between the tucking blocks, and at diametrically opposed points, the roll I25 is provided with center cutting blades I35, which function to cut the central portions of the web, and to finally divide the web into the sheets. The roll IZE- is formed similar to roll I25, but the same is provided at diametrically opposed points with radially extending tucker blades I37. These blades are adapted to ride into the tucker blocks, and serve as means for forcing the sheets at their central portions into the cylindrical ways I33 of the blocks. After the blades leave the blocks, the expansion of the paper within the cylindrical ways will hold the sheets on the roll I25 until the same are stripped from the roll by the combined stripping and packing fingers I30.

The roll I26, between the tucking blades Iili and at diametrically opposed points, is provided with cutting slots I 38, into which are adapted to ride the cutting blades I35 during the rotation of the rolls. This permits the convenient and expeditious servering-of the center portion of the web.

In the form of my invention just described, the paper is folded in a novel manner, and is held in its folded position in an extremely simple manner.

While I have shown the rolls provided with two cutting blades and two tucking blocks, it is to be understood that the rolls could be made on a smaller scale, and carry one cutting blade and one series of tucking blocks.

In Figures 18 to 21, inclusive, I have shown another and preferred means for cutting and fold ing the sheets transversely, and for stripping the sheets from the rolls. This form of my invention is similar to that form shown in Figures 15 to 17, inclusive, but it will be seen that I have considerably simplified the construction. As

illustrated, combined tucking and cutting rolls I25 and I26 are provided between which the paper web I2: is fed. This web is partially cut at its edges prior to reaching the rolls. The rolls I25 and IE6 are preferably of a greater diameter than that used in the other form of my invention. The roll I25 includes an elongated cylindrical body I28, having formed herein on opposite sides of its center annular grooves I29, into which are adapted to extend the stripping and packing fingers I30. These fingers can be of the same character, and may be operated in the same manher as the fingers H9 previously described. At diametrically opposed points the body portion of the roll I25 is provided with longitudinally extending grooves I3I, in which is fitted tucking blocks I32. All of the tucking blocks are provided with substantially cylindrical, longitudinally extending ways I33, which open out through the outer faces of the blocks, as at I34.

From the foregoing description it can be seen that I have provided a novel and simple mechanism for folding, cutting, and stacking paper sheets into receivers.
